BAMAKO, Mali (AP) - The battle to retake Mali's north from the al-Qaeda-linked groups controlling it began in earnest Saturday, after hundreds of French forces deployed to the country and began aerial bombardments to drive back the Islamic extremists.

At the same time, nations in West Africa authorized the immediate deployment of troops to Mali, fast-forwarding a military intervention that was not due to start until September.

The decision to begin the military operation was taken after the fighters, who seized the northern half of Mali nine months ago, decided earlier this week to push even further south to the town of Konna, coming within 50 kilometers (30 miles) of Mopti, the first town held by the government and a major base for the Malian military.

Many believe that if Mopti were to fall, the Islamists could potentially seize the rest of the country, dramatically raising the stakes. The potential outcome was "a terrorist state at the doorstep of France and Europe," French Defense Minister Jean-Yves Le Drian said Saturday.

France scrambled Mirage fighter jets from a base in neighboring Chad, as well as combat helicopters beginning the aerial assault on Friday. They have also sent in hundreds of troops to the front line, as well as to secure the capital. In just 24 hours, French forces succeeded in dispersing the Islamists from Konna, the town the fighters had seized in a bold advance earlier in the week, Le Drian said.

Malian military officials said they were now conducting sweeps, looking for snipers.

"A halting blow has been delivered, and heavy losses have been inflicted on our adversaries, but our mission is not complete," French President Francois Hollande said after a three-hour meeting with his defense chiefs in Paris. "I reiterate that it consists of preparing the deployment of an African intervention force to allow Mali to recover its territorial integrity."

However, in a sign of how hard the battle ahead may be, the extremists succeeded in shooting down a French helicopter, the defense minister confirmed. The pilot died of his wounds while he was being evacuated. The Islamists are using arms stolen from ex-Libyan leader Moammar Gadhafi's arsenal, as well as the weapons abandoned by Mali's military when they fled their posts in the face of the rebel advance.

They have outfitted SUVs with high-caliber machine guns, and have released videos displaying their collection of anti-aircraft weapons.

The Islamists have vowed to retaliate against French interests, and they claim to have sleeper cells in all of the capitals of the West African nations who are sending troops. Hollande announced that he had raised France's domestic terror threat level.

Online in jihadist forums, participants called for fighters to attack French interests in retaliation for the air raids. They discussed possible targets, including the French Embassy in neighboring Niger, one of the countries donating troops, according to a transcript provided by Washington-based SITE Intelligence.

The sudden military operation is a reversal of months of debate over whether or not Western powers should get involved in a military bid to oust the militants, who took advantage of a coup in Mali's capital in March to capture the north. As recently as December, U.N. Secretary-General Ban Ki-moon cautioned against a quick military operation. Diplomats said that September would be the earliest the operation could take place.

All of that went out the window this week when the fighters pushed south from the town of Douentza, which demarcated their line of control, located 900 kilometers (540 miles) from the capital. By Thursday, they had succeeded in pushing another 120 kilometers (72 miles) south, bringing them nearly face-to-face with the ill-equipped and ill-trained Malian military in a showdown that couldn't be ignored by the international community.

In a statement released Saturday, the bloc representing nations in West Africa, ECOWAS, said they had authorized the immediate deployment of troops to Mali. ECOWAS Commission President Kadre Desire Ouedraogo said they made the decision "in light of the urgency of the situation."

In Washington, a U.S. official confirmed that the country has offered to send drones to Mali. The official could not be named because he wasn't authorized to discuss the matter publicly.

Lt. Col. Diarran Kone, a spokesman for Mali's defense minister, said on Saturday that he was at the Bamako airport to receive a contingent of French special forces from one of their tactical units. Residents in the town of Sevare, near the line of control, said they had seen planes of white people arriving, whom they assume were French soldiers.

Hundreds of French troops were involved in the operation, code-named "Serval" after a sub-Saharan wildcat, officials in Paris said.

"The situation in Mali is serious," Le Drian said in Paris. "It has rapidly worsened in the last few days â?¦ We had to react before it was too late," he added.

French intelligence services had detected preparations for what they described as a "major offensive" organized and coordinated by al-Qaeda in the Islamic Maghreb, known as AQIM, and their allies against the towns of Mopti and Diabaly. After a large number of vehicles were spotted heading toward the strategic town on Thursday, France sent in its first unit to Sevare, a town adjacent to Mopti, to support the Malian combat forces, Le Drian said.

Then on Friday, Hollande authorized the use of French air power following an appeal from Mali's president. French pilots targeted a column of jihadist fighters travelling in pickup trucks, who were heading down toward Mopti from Konna. He said that the helicopter raid led to the destruction of several units of fighters and stopped their advance toward the city.

Overnight Saturday, air strikes began in the areas where the fighters operate, Le Drian said, led by French forces in Chad, where France has Mirage 2000 and Mirage F1 fighter jets stationed. Residents in the town of Lere, near the Mauritanian border, confirmed that it had been bombed.

Al-Qaeda's affiliate in Africa has been a shadowy presence for nearly a decade, operating out of Mali's lawless northern desert. They did not come out into the open until this April, when a coup by disgruntled soldiers in Bamako caused the country to tip into chaos. The extremists took advantage of the power vacuum, pushing into the main towns in the north, and seizing more than half of Mali's territory, an area larger than Afghanistan.

Turbaned fighters now control all the major northern cities, carrying out beatings, floggings and amputations in public squares just as the Taliban did.
